The 50mm bigger objective lens can collect maximum light to deliver bright and crystal-clear images. The multi-coated optics offer superior clarity and brightness. The BaK-4 Porro prisms enhance the image quality by maximizing the light reflections. So that, you can be sure that you will see every detail. Something we did have a slight issue with is the focusing wheel. Although it's easy enough to use, you do have to take quite a journey from one end of the scale to the other, which makes it slightly long-winded to refocus the binoculars for an object closer to you after studying something in the distance. We're also not convinced by the Nature DX ED 12x50's eyecups, which don't give much eye relief and seem something of a weak point.

OK, so this budget binocular is rather light on features too. And while it’s lightweight it’s not foldable. However, users do get adjustable turn-and-slide eyecups, and a familiar central focus knob, as well as multi-coated lenses that maximise light transmission to provide a sharper view. Also catching our eye is its slim and stylish single-hinged design, while a soft case, strap and eyepiece caps are included out of the box. Not the most sophisticated or powerful option here, granted, but a very, very affordable starter binocular for the casual observer. Binoculars largely come in two varieties when it comes to coatings: they’re either fully coated or multi-coated. In both versions, all lenses, glass surfaces and prisms feature at least one layer of magnesium fluoride or calcium fluoride. Binoculars with multi-coated optics are the most superior kind you’ll be able to find on the market, with at least one of the surfaces featuring several layers of anti-reflective compounds. Which binoculars are best for astronomy? The Thompson Center 12×50 binoculars are the perfect choice for anyone looking for a quality pair of binoculars at an affordable price. With its powerful magnification and large objective lens, it provides a clear, crisp image that’s perfect for viewing wildlife or sports events.The Nikon Action EX 12x50, weighing in at 2.3 lbs (1.04kg), is too heavy for long bouts of stargazing. The higher magnification will enhance any image wobble, so we advise using a tripod.

This binocular offers superior performance and value. The lenses are made from spherical multicoated eco-glass, which provides excellent image quality and clarity. The Porro prism attachment delivers high-resolution images of the targeted objects. The Nikon Action EX 12x50 are porro prism binoculars, which once dominated the market yet now form the basic design of the minority of binoculars. That's mainly down to portability. After all, the Nikon Action EX 12x50 has two tubes set far apart, with a Z-shape to the light entering their objective lenses. On the Nikon Action EX 12x50 that means a relatively wide design that can't be folded into a compact shape, as roof prism rivals can, and a total weight of 36.8 oz/1kg. For context, a similarly priced pair of roof prism binoculars shave at least a third off that. So why has Nikon chosen porro prism for these binoculars? Brightness. Porro prism binoculars generally need fewer fancy lens coatings to achieve a bright, detailed image, which is why the Nikon Action EX 12x50s are so cost-effective. The answer is yes, 12×50 binoculars are good for astronomy. High magnification and bigger lenses make it a good choice for astronomical observation. Again, they provide a relatively wide field of view and decent light-gathering ability.This HD 12x50mm binocular is one of the most versatile binoculars on the market. It’s perfect for hunters who need a lightweight and durable optic that can handle any condition. The binoculars are waterproof and fog proof, so you can use them in any weather.
